European Air War - The Gen

Am I correct in remembering that we determined that the road and and rail "wpt.dat" files serve no useful purpose?

Does the exe recognise "road" tiles for the purpose of vehicle interdictions? How does that work?

Those files are not used in the game, but there is a routine in one of the editor files (ZOOMEDIT.C) that saves the "railwpt.dat" file.
It was last modified in 1998.
They are not in the default "GameData" folder in UAW160.

Somehow truck convoys often seem to follow roads on the default tiles, but I could not find any reference to a tile ID relating to truck convoys.

Thanks Jel. Do we expect therefore that in new tile maps, truck/armour interdictions will take place on newly placed road tiles?

I will do some testing, but the other options are for truck and armoured convoys on invisible rail lines.

I did an ETO truck interdiction and got a convoy following a road.
Then I did one at ST Vito in the Med theatre. I saw no road tiles, but the convoy ran parallel and close to an airfield perimeter track.

I did another test at Buka in SPAW where there are no road tiles. The convoy was moving away from an airfield.

Thanks Jel.
